Oxidized carbon blacks and applications for lead acid batteries

Disclosed herein are oxidized carbon blacks, which can be incorporated into electrode compositions for lead acid batteries. In some embodiments, the oxidized carbon blacks have a BET surface area ranging from 650 to 2100 m2/g; an oil absorption number (OAN) ranging from 35 to 500 mL/100 g; and a vol...

Zusammenfassung:	Disclosed herein are oxidized carbon blacks, which can be incorporated into electrode compositions for lead acid batteries. In some embodiments, the oxidized carbon blacks have a BET surface area ranging from 650 to 2100 m2/g; an oil absorption number (OAN) ranging from 35 to 500 mL/100 g; and a volatile content of at least 5.5 wt. % relative to the total weight of the oxidized carbon black, as determined by weight loss at 950° C.
